The code is looking fine, more or less similar to the example.
But I get an error running the validator:
Element date
not allowed as child of element li
in this context
.
Using the time
-element seemed the most appropriate option to create machine-readable dates. But, it seems it doesn’t nest well within de li
-element.

Hi @carl_sys and welcome to the community 
Congratulations, great work! 
Here are a few comments:
- You can omit the last
<br>
in the first address since it automatically breaks the line.
- Self-closing elements don’t need the a slash at the end (e. g.
<br>
is okay).
- The semester dates should be in
<time>
elements not <date>
. <date>
doesn’t exist. (This should answer your question, I think.)
- You could wrap
The memoirs of Bill S Preston, <abbr title="esquire">Esq</abbr>
in a <cite>
element because it’s the source of the quote.
I hope that helps. 
Michael
